Overview
The Civil Aviation Regulations 1998, as part of the broader regulatory framework overseen by the Civil Aviation Safety Authority, were enacted to ensure the safe operation of civil aviation in Australia. The regulations address a range of safety concerns, including the issuance of airworthiness directives such as AD/BEECH 55/75 concerning the pilot and copilot shoulder harness for specific Beechcraft models. This directive was introduced to address the identified risk of improper washers in the shoulder harness “D” ring, which could lead to malfunctions and subsequent occupant injury during emergencies. The Civil Aviation Safety Authority mandates compliance with these directives to ensure that Australian registered aircraft meet international safety standards and to protect the safety of all occupants. The policy objective behind these regulations is to maintain high safety standards in civil aviation, thereby preventing accidents and ensuring the well-being of all individuals involved in air travel.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, pertains to the Beechcraft 55, 58 and 95-55 (Baron) series aeroplanes. This regulation applies to specific models and serial numbers of these aircraft, including Model E55, E55A with serial numbers TE-1078 through TE-1201, Model 58, 58A, 58P, 58PA, 58TC, and 58TCA with their respective serial number ranges. The directive mandates that these aircraft must comply with FAA AD 91-18-19, Amendment 39-8022, as referenced in Beechcraft MSB 2394. The requirement aims to rectify the potential issue of improperly installed washers in the pilot and copilot shoulder harness “D” ring, which could lead to malfunctions and occupant injury during emergencies. The compliance date for Australian registered aircraft is set as 12 December 1991, slightly extended from the original FAA effective date. This regulation applies nationwide, covering all specified aircraft within Australian jurisdiction.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, specifically addresses the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes through AD/BEECH 55/75. This Airworthiness Directive (AD) pertains to the pilot and copilot shoulder harness, with serial numbers for affected models detailed in the document (section 12/91). The directive applies to certain models of the Beechcraft 55, 58, and 95-B55 series aeroplanes, specifically those with particular serial numbers as outlined in the applicability section (section 1).
The AD mandates that actions be taken in accordance with the Technical Requirements of FAA AD 91-18-19, Amdt 39-8022, which is referenced in the requirement section (section 12/91). The directive specifies that compliance must be achieved as outlined in the Requirement Document, with a revised effective date of 12 December 1991 for Australian registered aircraft (section 1). This action is necessary due to the potential risk of improper washers being installed in the shoulder harness “D” ring, which could lead to a malfunctioning harness and subsequent injury to occupants during emergency situations (section 1).
The obligations imposed by this AD require aircraft owners, operators, and maintenance personnel to ensure that the specified models of the Beechcraft 55, 58, and 95-B55 series aeroplanes meet the compliance criteria detailed in the requirement section (section 1). This involves verifying the integrity of the shoulder harness “D” ring and making any necessary modifications to ensure the harness functions correctly. The directive references Beechcraft MSB 2394 as a resource for compliance (section 12/91).
Failure to comply with the AD may result in serious safety hazards, as the directive is designed to prevent malfunctioning shoulder harnesses that could lead to occupant injury during emergencies. The AD does not explicitly state penalties or consequences for non-compliance, but the potential for serious injury and regulatory action underscores the importance of adhering to the directive. The Civil Aviation Regulations 1998, along with associated Australian aviation safety laws, may impose additional penalties or consequences for non-compliance with ADs.
